According to a story in the Wall Street Journal, Facebook's revenue has eclipsed that of Twitter and observers are attributing this to the growing number of video ads on Facebook. Last week Twitter "badly missed" its expected earnings because big brand advertisers are not increasing their spending.
They are, however, on Facebook which is very friendly to video ads.
Frankly, there are two things going on here. One is the decrease in ad spending and the other is that Twitter is more of a niche social media site than is Facebook. Facebook is where all your friends gather and share things. Twitter is quick hits of information or opinion, often posted by people you don't know.
And, I find it hard to believe there are that many people who click on video ads. Static ads are bad enough, but video ads? Come on.
Here's the link to the WSJ article but you won't be able to read it unless you're a subscriber which is irritating because if a news outlet thinks something is important enough to Tweet or link, they should allow the entire story.
